Machine learning predicts elastic behavior of multi-component alloys using information from simple two-component alloys

Researchers improve the efficiency of face shields by coating them with a hydrophobic layer.

Face shields act as primary barriers to airborne disease-carrying droplets. They are effective in closed spaces such as aircraft cabins and offices where chances of exposure to the droplets from speech, breath, cough or sneeze are high. Face shields have assumed importance during the COVID-19 pandemic, and simple face shields made from plexiglass plastic or polyethylene terephthalate (PET) are available for public use.

A new cooling model gave better predictions of the strength and ductility of cast iron

Cast iron, an alloy of iron with carbon, is widely used for making machine and automobile parts. In its liquid form, it flows easily, hence can be poured into moulds, offering intricate detailing in the part shape. It may be less ductile and malleable than wrought iron or less stiff than steel, but it has a lower melting point than other forms of iron and cannot be compressed easily. 

Researchers propose a biosensor model that captures the effect of the fluid-sensor interface charge.

Researchers probe properties of the new material, say better for micro- and nanodevices.

Air travel these days has become pretty smooth, with passengers feeling very little vibrations while seated in the cabin. Engineers install palm-sized devices on the aircraft wings and cabin windows to dampen the vibrations from the huge aircraft turbine engines and the surrounding atmosphere. These devices are made of piezoelectric materials, which generate a large vibration-cancelling force when an electric signal is applied.

New experimentally validated model accounts for manufacturing process variations while designing ultra-dense electronic circuits.
